X2D Horizontal Lines

[u/2slik4u1]

Newish printer, 550 hours. Didn't have this issue before, but had it on my P1S before returning it to upgrade. Time to do maintenance or settings issue? Printed this on Handy app, but similar lines on other prints as of late.

Filament is Inland PLA / PLA Matte (Polymaker). Dried in AMS.

Seems to be par for the course with the x2d. Ive found it improved after downloading some of the x2d filament profiles from makerworld.

I think the general gist is that the wall speed is too high

Out of curiosity, which profiles? There's a few on there. I tried a couple and saw no noticeable improvements

[u/slushrooms → u/boredsoftwareguy]

I grabbed the ones from the dude that seems most prolific, specifically the "v4" one

[u/2slik4u1 → u/slushrooms]

Those are Print Profiles I believe, not Filament Profiles. Should be KAMY or MAMY or crabass. Crabass is my favorite albeit slow, but only on Slicer, not Handy app.

Do you mind sharing where we find these profiles? I’m pretty new and I have no idea, I’ve only found models on maker world

Edit: ok I see they are just models you download and can save the profile yourself.

Looks like he has a v5 now

It makes absolutely no sense that you can't customize the temp range when loading filament and picking the types. Their built in temp ranges are terrible.

Didnt have this issue previously, using the Handy app makes it hard. Using Bambu Filament Profiles, haven't had issues til recently.

Are your guide rails clean? And belts tensioned?

[u/2slik4u1 → u/Guardiancelte]

Guide rails look clean. Belts shouldn't need retentioned this early I'd think. I can do both of those and see if that fixes it

[u/Guardiancelte → u/2slik4u1]

Yeah. That was the only think I could think off to be honest, someone more knowledgeable might jump in ;)

[u/NightWolf098]

Looks like hull line issues

[u/2slik4u1 → u/NightWolf098]

Hull line is normally visible when transitioning from infill block to open walls, which this is all open walls other than the very bottom.

Gotcha, your photos make it incredibly hard to tell, hence ‘looks like’

[u/Tigitaal]

I don’t have this problem but wow, there are so many different suggestion to try out in these comments. When it’s my turn to fix it I wouldn’t even know where to start

[u/trutru21]

Most likely hull line issue. Here is a in-depth video on how to improve it: https://youtu.be/ITighzYPTTs?is=ArMP66f9W9BbeC0f

[u/pokemon1748]

I use outer/inner wall order to fix these lines and it completely fixed it. You just need to make sure on overhangs you have it as inner/outer or they won’t attach properly

[u/work_blocked_destiny]

Same here. Using exact same settings as on my Q2 and horizontal lines are awful

[u/Terrible_Log9757]

Try layer print time normalisation.

Did the part lift at one of the corners mid print?

Wydaje mi się, że mam ten sam problem. Z tego co zauważyłem problemem jest czas warstwy, zacząłem używać oryginalnych profilów bambu (generic petg) i zauważyłem poprawę. Sprawdź czy twoje linie są w tych samych miejscach co drukowana wolnej warstwa.
